To all whom t may concern."

Be it known .that we, Lrrrarnn BAUM and Clientes Saisonen, citizens .ofthe United States, residing ,at `yfashington, in the District of AColuniloia, have invented certain new and useful Improvements in Locksfor Autornobiles, of which the following is a specication.

Qur inyention relates to new and useful improvements in locks, and moreparticularly to locks for automobiles, and the primary object of theinvention is to provide a device .0f this `character which may bereadily and quickly applied to the steering post of an automobile toprevent the theft of the machine. Y

A :further `object of Athe invention resides in the provision of adevice which may be Carried on the steering post in its ineffectiveposition and which, when given a partial rotary moveln nt, will be.eifectively disposed to prevent .the rotation of the steen ing post.

Another object resides in providing a sleeve member formed in sectionshinged one to the other with means to lock the same on a stationaryobject, and still another object resides in providing a spring forcedpin on one of said sections adapted to enter alining openings in thesteering post and casing therefor.

A still further objectis to province device which is extremely simple inconstruction, inexpensive to manufacture and one which will he veryeficient in operation.

With these and other objects in view, our invention consists in thenovel features of construction, combination and arrangement of parts aswill be hereinafter referred to and more particularly pointed out in thespecification.

ln the accompanying drawing forming a part of this application: Figure 1is a side elevation of an automobile, showing our device applied to usethereon. Fig. 2 is a vertical section through the steering post, showingthe device in its effect-ive position thereon. Fig. 3 is a perspectiveview of .the device removed, and Fig. 4 is a horizontal section throughthe steering post, showing our device in its ineffective positionthereon.

In describing our invention we shall refer to the drawing, in whichsimilar reference characters designate .corresponding parts throughoutthe application and in which- Il indicates an automobile of the usual orVany preferred type having the customary steering post 2 thereon, saidpostl being of the Iusual type comprising the inner movable post 3carrying the operating wheel and the outer tubular casing 4. Ourinvention contemplates a means to prevent the rotationoa this inner post3, and to this end said post,

which in most instances is hollow, is pro-.

vided with an opening 5, while the outer casing 4 is also provided withan opening 6, said openings being so arranged as to aline with oneanother` at a predetermined position of the steering post and front axleof the machine (not shown). A sleeve member 7 comprising a pair ofarcuate sections 8 and 9 hinged lone to the other is adapted to beapplied to the post and a socket 10 formed as an extension on the freeend of the section 8 is adapted to receive a rotating locking bolt 11therein, said bolt being carried on an extension of the free end of thesection 9 and operated by means of a key 12.

Threaded on the section 9 is a tubular eX- tension/13, the outerl end ofWhich is closed, while the inner lend thereof terminates in a contractedopening 14. A locking pin or stud 15 slidably mounted in said extensionhas formed intermediate of its ends a collar 1G which limits themovement of said pin and encircling said pin between the collar and 'theouter closed end thereof is a coil spring 17. The tendency of thisspring is to force the pin or stud 15 inwardly toward the axial centerof the sleeve, but the collar 16 will limit such movement and if thesleeve 7 is locked on the steering post in its ineffective position, asshown in Fig. 4 of the drawing, said pin will be forced inwardly againstthe tension of the spring.

The sleeve member 7 is of such a diameter when locked as to be capableof a rotary movement on the steering post, and We have provided meansfor retaining'. the device in position on the post so as to allow thepin 15 to enter the alining openings 5 and G when said device isrot-ated. To this end the section 8 is provided withma vslot 18 in thesaine horizontal plane with, the opening 14 in the section 9, and asmall screw 19 is disposed through this slot and engaged with a threadedopening 2() in thev outer casing Cit throiigh the slot 18 of the sleeve7 and engaged with the opening 2O of the outer casing 4t, Whereuponthesections 8 and 5l are clamped together and locked on the post in aposition as show-n in Fig. fi, so that the stud or pin 15 is beyond theopenings 5 and 6. The key l2 I is then removed and the device allowed toremain. in this position on the steering post until such time as it isdesired to lock the machine, and in this sense the. device may be saidto be permanently carried on the steering post. When it is desired tolock the machine, the operatorv merely gives the sleeve 7 a partialrotation, it being understood that the openings 5 and 6 are alreadyalined, and as the pin o'r stud l5 registers with said openings 5 and 6the same Will spring therein and prevent further operation of thesteering post. The operator may noW leave the machine Without danger ofhaving same stolen and upon his return it is onl) necessary to insertthe key and operate the locking bolt vto separate the sections 8 and 9.A separation of said sections Will permit the pin l5 to be disengagedand allow the sleeve to be again rotated to its initial position andlocked lfor further use, as shown in F ig. 4.

`From the foregoing, it will be seen that W'e have provided an improveddevice Which will be positive and etlicient in its operation t-o preventthe theft of automobiles and it will further be seen that the same issimple and durable in construction and inexpensive to manufacture.

While We have particularly describedA the elements best adapted toperform the tunetions set fort-h, it is obvious that various changes inform, proportion and in the miner details of construction may beresorted to Without departing from the spirit or sacriiicing any of theprinciples of the invention.

Having thus described our invention, what We claim is:

l. The combination with a stationary tubular member and a rotatablemember there- Within, said members having openings therein adapted forregistration; of a sleeve formed of hinged sections, means to securesaid sections together on the stationary member to permit rotationthereon, means to guide and limit said sleeve in its rotative movement,and a yielding projection on the inner tace ot' said sleeve adapted toenter the registering openings of said' members.

2. lhe combination with a stationar tubular member and a rotatablemember t erevvithin, said members having o 'enings therein adapted foralinement; of a sleeveformed in sections hinged one to the other, oneoit said sections being provided with 'a slot..

needles therein, means extending through said slot and engaged With saidstationary member to adjustably retain said sleeve on the latter, ayielding projection extending from the inner face of the other sectionof said sleeve and adapted to enter the alining openings, and means tolock the sections of said sleeve together,`

3. rllhe combination with a stationary tubular member and a rotatablemember there- Within, said members each having an opening thereinadapted for alinement; of a sleeve comprising a pair of hinged sections,means to lock said sections together, means to movably retain saidsleeve on the stationary member, and a spring held stud projectingbeyond the inner face of one of the sections o said sleeve and adapt-edto enter the alined openings of said members.

4. rlhe combination with a stationary tubular member and a rotatablemember therewithin, said members each having an opening therein adaptedfor alinement, of a sleeve comprising a pair of hinged sections, meansto lock said sections together, means to retain said sleeve on thestationary member and permit a partial rotation thereon, a tubularextension carried on one of said sections, and a spring forced stud in said eX- tension adapted to project beyond the inner face of said sectionand enter the alining openings of said members.

5. In a device of the class described,-the combination with stationaryand movable members, each having an opening therein adapted forregistration With one another; of a sleeve member loosely applied tosaid stationary member, means to limit the movement ot' said sleevemember, and means yieldingly carried on said sleeve member and adaptedfor engagement with 'the registering openings of the first mentionedmem- Abers upon movement of said sleeve member 6. ln a device of theclass described, the combination With a stationary and a movable member;of a sleeve applied to said stationary vmember and partially rotatablethereon, means to limit the rotative movement of said sleeve, and meanscarried en said sleeve adapted for automatic coperation with saidstationary and movable members to lock the same together upon-movementof said sleeve to a predetermined point.
